STAPLE FORlVIING AND DRIVING MACHINE.

SPECIFICATION forming part of Letters Patent No. 573,329, dated December 15, 1896. Application led February 21, 1896. Serial No. 580,287. KNO model.)

To all whom, t may concer-n,.-

Beit known that I, WILLIAMfH. JACKSON, a citizen of the United States, and a `resident of Fall River, in the county ofBristol and State of Massachusetts, have invented certain new and useful Improvements in Staple Forming and Driving Machin es, of which the -following is a specification.

This invention relates to new and useful improvements in machines for converting wire into staples and then driving the same into any suitable material.

It is the object of my invention to improve upon machines of the above class and to construct amachine which is particularly adapted quence require numerous repairs which must be made by a skilled mechanic. Besides greatly simplifying this classl of machines I improve the detail mechanism in sucha inanner as to accomplish more perfect operations. I also improve upon the staple forming and driving mechanism in such a manner that it will operate upon a curled-brim hat as desirably as upon a straight brim. The importance of this feature will be apparent when it is considered that there are a great many more curled-brim hats manufactured than straight ones.

Mymachine is constructedin such a manner 'as to support a hat while being operated upon and to permit the same being shifted takes the wire from the reel, cuts off blanks the desired length, converts said 'blanks into staples,,forccsthe same through the band and hat-body, Vand nally clenches lthe points firmly into the'material. The machine is operated `by one attendant, who stands atthe front of the machine and manipulates the It. automatically hand and foot levers 4in ,a manner to permit `of the hat being placed upon its rest and to shift the belt from one pulley of the drivingshaft to the other. Y f;

IVit-h the aboveobjects'in view I have devised the novel and simple construction illustrated in the accompanying drawings, which form a part of this specification, and upon which similar reference characters denote like or corresponding parts upon the several gures, and of which- Figure 1 is a plan view of my machine complete, showing in dotted lines a hat thereon. Fig. 2 is a front elevation of the machine, the posiion of the parts agreeing with Fig. 1. Fig. 3 is a detail side elevation of the swinging bracket carrying the hat-support. Fig. 4 is a sectional plan view of the wire feeding and cutting mechanisms. Fig. 5 is a detailed sectional plan view of the mechanism for forming and driving the staple. Figs. G and 7 show vertical sectional views on line x of Fig. 4, looking in opposite directions. Fig. S shows different stages of the operations upon the wire.

Referring. to the numerals marked upon the drawings, 1 indicates the top framework, and 2 legs supporting the same. 3 indicates the driving-shaft, mounted in bearings #l ofthe frame and provided with a tight and loose beltpulley 5 and 6, respectively. Said shaft is further provided with a small beveled pinion 7?, which meshes with and drives a large bevel-pinion S, secured to shaft 9, placed. at a right angle to the main driving-shaft and j ournaled in suitable bearings l0 of the frame 1. Upon this shaft 9 are secured cams 1l and 12 and eccentric 13, each of which operate certain sets of mechanism, the first of which I will next describe as follows, and what I term as feeding mechanism:

Wire-feeding mechanism- The cam 11 on v the near end of the shaft 9 is a double-purpose cam, and serves to operate both the feeding and cutting mechanism. I will accordingly first describe its connection with van opl eration of the feeding mechanism, and then describe the manner of severing the blanks from which the staples are formed. To the frontof the frame 1 I secure a bracket 14, (see IOO Figs. 1 and 2 and details,) containing the staple forming and driving mechanism, as will be laterV more fully described, but which in part consists of a hole 15, through which the wire is fed, and against which it is cut off the proper length. Adjacent to the inner face of said cam 11 is a feed-lever 16, pivoted to the frame at 17 and bearing a lug 18, which is firmly retained against the side of the cam 11v by means of the spring 19. Within said side of the earn 11 is formed an inclined recess 20, sufiicientl y large to allow the lug of the feedlever to drop therein with each rotation of said cam, thereby throwing forward the free end of the feed-lever. By reason of the inclined surface of said recess 2O 'the lug'18 immediately rides off of said recess with the movement of` the cam, thereby swinging the outer end ofthe feedlever back to 'its normal position. Aswill be observed; (seeFig. 4,)` the lever 1G is provided with a feed-clutch 21, consisting of an` enlargement. havinga conical rrecess therein, `,terminating in .a small hole .through which theV wire passes.- Saidrecess is further provided with a `friction-ball 22,'the diameter of whichis-smaller thanthe` recess, thus allowing the wire to pass between said ball and the wall of saidfrec'ess,whereby the wire is'firmlyclampe'd within saidclutch and thus fed` forward withfthe" movement of theil'ever. To the'extension23of-theframe is secured-asimilar clutch-24, which serves as aretainingcl utehinsteadof't affeed-clutch, it being obv-ions that, its ballrwill allow` the wire` tobe freely drawnI therethrough by the operationof the feed-clutch on the leverl 1G, butwillreadily check anybackward movementof the'wire caused bythe returnof the feed-lever.

Wt'fl'e-cutt'ng.mechanism.-Cani 11, above mentioned, is*furtherfprovided with a peripheral enlargement 25, which is in line with a-ndl operates the cutting-slide 2G,.movablyy fitted in guidesy 27, secured tothe bracket'14before mentioned. SaidY slide is normallyl held against the periphery ofsaid cam'bymeansofaspringS, one end--of whichis secured thereto,-.the opposite end ybein g secured to the bracketl4rraforesa-id. 2i) indicates the cutting. edge of thisfslide, whichvser-ves to sever` the wire by operating upon it against. the wall ofr thc hole 15 in the bracket 14, thus severinga-blank at regularv intervals;`

Staple forming cmd, driving,mechanism.- Parallelwith theshaft `9 isarock-shaft 30; journaled-in bearingsl-oftheframe. and inf the bracket 14, secured thereto. Said' shaft is afforded a rocking.,movementbyreason'of its counectonlwith the. previously-mentioned cam-shaft 9,.which'connection'consistsof: an eccentric '13; secured on said driven shaft and bearing a connecting-rod having strapsf32 at one end encirclingvsaid. eccentric,.the oppesite end Ofsaid'rodbeingconne'cted to an arm- 33 on said rock-shaft. 'llliusit will( be obvi ous` that withy each rotationof the driven shaftQ-the shaft'y 30 will be given a-rocking motion, which'movements, throughy the connection of said shaft, serve to form the staple and drivethe same into the material, as will be next described.

The bracket 14, before mentioned, is made in two parts, as shown in Figs. 6 and 7,1- and which I indicate by 34 and 35. The inner end-of this bracket' is providedwith a recess 3G upon its under side, which recess in turn has a semicircular groove 37 in each side thereof. The end of the rock-shaft 30, before mentioned, extends into said recess and bears therein an operating-finger 3S, as clearly appears in Figs. 5 and 6.of the drawings, and which forms and drives the staples. The wirefromwhich the staples are made is fed into the recess the desired length through the small hole (indicated-135715)fand against the shouldery 15, (see'Fig: 4,) after which it is cut off by the cutting mechanism. The rockshaft SO `is next operated'inafmanner to move the finger backwardffrom the positionV shown in Fig. G, whereupon said finger will come intocon'tact' with the center ofthe wirel blank, the end of which is then detainedin the hole 15 and shoulder 15, thusfolding the same into`practically a U--shaped staple, the free endsV thereof being drawn' into the lgroove 3S, thus retaining and guidingthe same'. After the staple has been formed as above it is carried upward in-saidgrooves-until it comes into contact with the spjring like strippers 39, which serve to detain the progressof and strip the staple while the finger passes by it, after which the movement of the `finger is reversed and the under side of said finger engages the head: of the .staple and i forces the same. down while it is properly guided into the band and hat through the grooves before mentioned.

llfecmsifor Supporting the Ldt.--As previ ously stated, I provide means for supporting. the hatk while being' operated upon,l which mea-ns consistsv in a swingingI bracket 40,

hin gedtoa vertical rod41, movablyiitted in` ways-42'ofthe'frame Said bracket isfurther provided witlrafhandle 43, by meansfof which the'operator swings the saine out and in for the. purpose of'removing from and putting'afhataupon the: supportingsarm proper, whichI indicaterby 44. This-support is provided with a yieldable clenching-plate 45, which inV practice *lies against theu nder rside ofy the-hatand serv-es to deiect the course of the endsof the staples andthus-turnthe same backinto the` hat-body. Adjacent' to the plate above mentionedl provide a= guide 4G, against which the edge of the hat rests during the'. operationsI andi against whichy it is movedbetween the operations;

The. bracket 40 above mentionedl islpr'ovidedwith'means-for rigidly-'locking it in its closed position, which consists in aspringf actua-ted* slidev 47,- secured inV ways ofv the bracket, a'ndxdesigned to normally engagea notchf4S"inone of the legs2`of: the machine'.

Saidslide is connected by means of a wire 49 withthe `finger-lever 50, pivoted adjac'entto' IOO will `be apparent that in order to swing open the support, as shown in dotted lines, (see Fig. 1,) the attendant would first manipulate the fingerflever 50 in a manner to disengage the sliding catch, thus releasing the bracket and permitting it to be swung out by the operator.

In order to permit the hat to be turned upon its support and thus shift its position to receive successive staples, I provide means for alternately raising the rod 41, its bracket and hat-support, against the resistance of gravity, consisting substantially as follows; The lower end of the rod 41, before mentioned, projects through the lower way 42 and rests upon the horizontal arm of a bell-crank lever 51, pivoted to the frame at 52. The remaining arm 53 of said lever extends upward and rides upon the surface of cam 18, before mentioned. It will accordingly be obvious that by reason of the irregular surface of said cam the bell-crank lever above referred to will be swung upon its pivot, forcing the vertical rod 41, its bracket and support, upward from the position shown in Fig. 2 until said support and the hat carried thereby are moved up against the staplesdriving mechanism for the purpose of receiving a staple, after which the advanced periphery of the cam allows the support to drop, during'which time the operator shifts the posit-ion of the hat to receive the next staple. In order to provide a yielding connection between the bracket 40 and its rod, I secure a collar 54 to said rod, and support thereby a coiled spring 55, which in turn serves to support the bracket 40 in such a manner that when said rod is forced up the spring will act upon the bracket and yield ably raise the same until its support comes into contact with the bracket 14 of the staple-former. g

The starting and stopping ofthe machine are accomplished by means of foot-power applied to the treadle 56, having a wire connec tion 57 with a belhcrank lever 58, pivoted at 59 to the frame. The upwardly-extended arm of said bellcrank lever is provided with` a fork G0, which serves to straddle the belt (not shown) and shift the same from the tight to the loose pulley, or vice versa, by means of the operation of the treadle, thus starting or stopping the machine according to said treadle movement.

The operation of my machine is as follows: Presuming the machine to be in the position shown in Fig. 1, the attendant would by means of his right hand manipulate the handle 43 and its finger-lever 50 in a manner to throw open the bracket 40 and its support; then place a hat upon the clenching-plate, as shown in dotted lines, and against the guide 46; next swing the bracket back to its normal position, where it is locked. The belt-shifter is next operated and the machine started `in motion. The first operation is that of the 4cam 13, which raises the bracket 40 and the hat contain ed thereon up against the bracket 14, after which the finger 3S operates to form the staple and drive the same `into the hat. The instant the above is accomplished the cam 13 allows the bracket to drop sufficiently to permit the operator to move the hat and its band upon the support a short distance, when said cam willagain raise the bracket to its elevated position, when the former operations of forming and driving the staple are repeated. The staples are in this manner repeatedly made and inserted and the bands and sweats attached to said hats by means of such repeated operation, the number upon each hat varying according to the class of work and size of hat. After the desired number of staples have been inserted as above the belt is shifted back upon the loose pulley, the bracket 40 thrown open, and the finished hat removed therefrom.
